Divorce

Hi, I am residing in Bangalore. I got arranged married in 2018 February. I found soon after marriage that my wife used to have many boyfriends (for which I had no evidence as I heard it from some of my friends). After few months into my marriage, I noticed that she was in touch with her old boyfriend. I confronted her about this and strictly said not to call any boys. Then, after some days she started flirting in front of me with unknown guys. I asked her again not to do such things. She went to her parents said to them that I’m very possessive and I keep doubting. My father-in-law came and shouted on us only (he has some political background). This thing went on for six months. Her parents come to my house and somehow blame us for her. She started ordering me and my parents to do thing which she likes and she also attempted thrice to suicide just to scare me. This March of 2019, my father got myocardial infarction due to this stress on my family(he is 68 years old and had a heart attack once 25 years back). After his discharge to home, she started shouting “why did you spent your money for this old people”. I got really frustrated and asked her father to calm her, but that asshole came to my house and started yelling at my father. My father collapsed again. I lost my my mind and scolded my wife and father-in-law to get the fuck out of my house. He and my wife said they will file 498 case on me and left my house four months ago. My father-in-law and brother-in-law also threatened to kill my family which I have recording of. In this process, I lost my job and in home for three months now. I need help. Please how to prove mysef and my family are innocent. If I’m applying for divorce, should I have to pay her.
